1)A metropolis that is littered with high technology like computers and robotics to the point it becomes part of the city's culture and/or religion.

(Today's cities only display the early stages of this phenomenon in the form of large TV screens, lights, people with robotic prosthetic limbs and various other technolgies.)

2) A technopolis is a city where robots and cyborgs are so commonplace that complex computers, robotic parts and artificial intelligence programs can be seen in trash bins and/or are sold freely on the street.
